Along with Broque Monsieur, Broque Madame and Broggy, other members of their kind appear in Mario & Luigi: Dream Team, and two notable Brocks, Brickle and Britta are introduced. It is in this game that the species is first officially named. Notably, many Brocks are seen wearing costumes resembling the Zeekeeper throughout Pi'illo Island.

Even though the Brock people have mouths, they don't seem to have any facial expressions, even if they are panicked. They only express their emotions when they jump when the player interacts with them, or shake if scared. The only expression they make with their eyes is when Bowser and Antasma use the Dreambeats to put them to sleep.
